`DETROIT, MICHIGAN ENAMEL METALLIC TILE Appuaaon ma umn s1, leso. serialNo. 440,595.

' The invention relates lto tiles suchias are used for facing walls inboth interior and exterior finish/and it is the object of the inventionto obtain a construction formed from enamelled sheet metal having manyadvantages over the clay product. To this end the invention consistsinthe construction as hereinafter set forth. y

In the drawing:

Figure '1 is a perspective view of my improved tile;

Figure 2 is a cross section showing the tile as lald in a wall;

Figure 3 is an enlarged cross section through a portion ofl a tile andthe joint between the same and adjacent tile;

Figure 4 is anenlarged perspective view' of the corner constructlon, and

Figure 5 is a plan view of a portion of the blank from which the tileisformed.

My improved construction is formed from a sheet metal blank A which ispressed 4and fashioned to form inwardly extending flanges lB on itsseveral sides and which for a portion faces. The external surface F issmooth,

and glazed to produce the desired appearance but the internal surface Gis-rough,'thereby forming a better adhesion to the cement or plaster ll.During this enamelling process it is necessary to heat the metalto atem-v perature where' there would be a tendency for lit to sag. Such aresult is, however,

venting any crackin e'ectually prevented, first by the outward bowing ofthe front face and second, vdue to the fact' that a-portion of the. angeB is continuous and integral `around the entire perimeter, therebyresisting any outwajrd thrust due to the sagging of the bowed portion.As a consequence, the finished tile are all of the slightly convexedform which pro-v duces a pleasing appearance in the wall.

Another' important feature of my improvement is the means which I employfor preof the enamel at the corners of the tile. uch a cracking wouldoccur if the flanges B were separate from each other or in other words,if` the gore D were to extend completely'to the bend between the liangeand the front face. With my construction, however, the fact that. thedepending ange B is integral around the corners and that the enamelextends continuously over the front face and down the integral sideflanges, effectually prevents the forming of any cracks at the corners.

To complete the tile, a cement or plaster core is filled in between theflanges B, being retained by Lthe obliquely converging portionsfE ofsaid ianges. 4This core may made -either prior or during the setting ofthe tile i'n the wall, preferably the latter. Thus the operator mayplace. the plastic filling in the space betweenthe ilanges of the tile.and then place the structure against the the wall surface and retain thetile in osition. The joint I-I between adjacent ti es is' also filledwith a cement and by reason of the oblique portions E, the bodyof cementbetween tiles is enlarged at its inner end, which` adds to its strength.The tiles may be laid against any surfacewhich is suitable for refceiving plaster or cement..`

What I claim as-my invention is: 4

A tile comprising a sheet metal blank gored at the corners and pressedto form a 'wall. The plastic filling will thus' knit to lfront faceand'side anges, said side flanges o ,heilig of e depth greater than thedepth or.

the gores to form e portion eontmuoue around the corners, presenting anside anes and around the corners for re' ceiving t e enamel finish, thegered portions of said blank being beni'l ohquely to e0nverge towardsthe center of the tile to foriumA Yinclined triangular-shaped openingset the .corners, and said sheet metal structure having aA vitreousenamel surface 'outside and inside.
